. ?His employee has also been working on British cars for years, and is a =
transmission specialist. ?They've rebuilt literally 100s of transmissions =

 400 PSI, but it needs to be 490 to over 500, I think they said 520. ?They=

a pump that would shift softer because I've got a torquey engine and the o=
